2001
It is conceivable that the 14 records for this species included an identical bird, accompanied on two occasions by one other! Information about age might have illuminated the problem, but not necessarily so. Nevertheless, I plead guilty! All but five birds haunted Sandy Water Park and the dates for these were: January 6th and 31st; February 3rd, 20th and 28th; 16th April; 15th July; 26th October and 3rd November – 2 this time. Away from Sandy Water Park, 1 was at Upper Loughor on 4th January while Llanelli Beach held 1 on 17th February and 24th July, with 2 there on 15 July. On 2nd October 1 was at Burry Port Harbour.

2002
In January 3 adults at Sandy Water Park. on 19th. A first winter bird was seen on 21st February. Singles at Machynys and Burry Port on 10th and 29th July respectively. 1 at Upper Loughor on 9th August. A juvenile went almost unnoticed among Black-headed Gulls at Pembrey Beach on 20th August. An adult at Sandy Water Park on 2nd September. Singles there again on 10th and 27th October. A single adult, presumably the same as the last bird, present on 12th November and 17th December. Details of birds at Penclacwydd are: on 17th February 1 first winter; on 20th and 21st June 1 adult winter; a total of 5 birds noted throughout June; 10 birds in July. being 3 first years, 2 second years, 4 adult summer and 1 adult winter.

2003
An adult at Sandy Water Park on 9th & 20th January and 1st February, presumably the same bird. A first summer bird at Penclacwydd on 26th May 2, plumage unspecified, near Copperhouse, Machynys on 21th July. An adult at Penclacwydd and 4 unspecified plumaged birds near Copperhouse, Machynys, all on 24th July. An unspecified plumaged bird was at the Upper Loughor Estuary on 25th October. Sandy Water Park had 2 adults and a first winter on 3rd November and an adult on 9th December. Penclacwydd records were: one first year on 16th May: same from 20th to 24th May at least live birds throughout June and July: a bird with a green ring (3HJ6) on 21st July and 7 adultss on 25th July.

2004
Adult Sandy Water Park January 11th, 2nd winter North Dock, Llanelli February 1st, 1st summer Afon Lliedi, Llanelli March 2nd, 2nd summer Penclacwydd April 7th, 1st summer & 2nd summer Penclacwydd April 29th -May 24th, adult North Dock June 7th, adult Burry Port July 11th, 4 adults & 2 2nd winter birds Sandy Water Park August 28th and adult North Dock Llanelli November 27th. The two immatures at Penclacwydd in in April/May built a nest and were sitting but unlikely there was any result. A peak of 15 at Llanelli Beach on September 9th is also worth mentioning.

One wearing a green ring at Llanelli Beach August 27th had been ringed as a chick at a new colony at Zandvlietsluis, Belgium on May 9th.

2005

2006
This species is becoming so numerous that it is difficult to mention individual records. Frequently used sites were Burry Port Harbour and Sandy Water Park. At the latter site c30 were present July 6th. Penclacwydd produced a number of records peaking at 22 June 15th. At this site birds were noted nest sitting but no breeding was proven.

2007
At Penclacwydd 18 different birds were recorded in June and included 4 colour ringed birds all of which seem to originate from Belgium. There are so many records of individual birds now that it is impossible to know just how many are present. A group of 29 were on Llanelli Beach September 27th.
